To @ZZ whom, t may concern.'

Beit known that I, Zronanran V. PUnDY, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky,l have invented certain new and useful Improvements in Horseshoe-Machines, of which the following is a specification, reference being had ltherein to the accompanying drawings.

My invention relates to certain improvements in machines for making horseshoes, and has for its objects to obviate certain objectionable features in machines heretofore used, and, besides simplifying` the maehanism, strength and ease of operation are obtained, as will be hereinafter more fully set forth.

In the accompanying drawings, Figure l represents a vertical and longitudinal section through the machine, showing the main driving-shaft and the cam thereon in elevation. Fig. 2 is aplan view ofthe earn on the main driving-shaft. Fig. 3 is a plan view of the bed, the upright frame being removed. Fig. 4 is aplan View of the bottom of the piercing-tool; and Fig. 5 is a front elevation of the piercing-tool, showing the guides and a portion of the posts of the upright frame.

, A. represents the bed of the machine, which is provided with an opening, B, near one end for the purpose hereinafter specified. The other end or half of the bed is cut away or recessed from the opening to the dotted lines shown on Fig. 3, the parts vleft intact forming a support for the plate @which is also cut away, as shown, forming an opening with slanting sides. On each side of this opening are the curved slots D.

That portion of the bed which surrounds the opening B is recessed to receive the sliding carriage E, which moves over the opening, and is retained on the bed by the guides F on each side ci' the recess in the said bed. This carriage has a groove or recess on its under side, in which is pivot-ed, near the center of said carriage, one end of each curved arm G. Near the other end of each of these arms, on the under side, is the slot H, at the inner end of which, in a proper recess,is the frictionroller I. XVhen the carriage is drawn back,

5o the slots in the arms coincide with a slot, K,

(No model.)

through one side of the bed A. It is through these slots that the bar from which the shoe is to be made is passed.

` Between the slots in the arms and the free end of the same are the friction-rollers L, which pass through the slots D in the plate C and form anti-friction bearings or guides for the arms which pass under the plate.

M represents a friction-roller in the forward end of each arm, and bearing against the sides of the recessed portion of the bed as the said arms are advanced.

N represents a circular piece let in the recessed portion of the bed, and on which rests the shoe-die O, which has a circular outward bevel on the toe and extending partly on the sides. This die has perpendicular sides above the bevel before mentioned, and is also provided on top with another bevel, as shown. From the top of the die, near the toe, is raised the guide l?, for the purpose hereinafter specified.

R represents two upright posts-one on each side or' the bed. They are connected by a cross-piece, S, forming a frame, which is provided on top with a guide for the reciprocating frame T, which supports the piercing-tool U. This tool is recessed on its under side, as shown in Fig. 4, the recess being of proper shape to receive the die O, over which the piercing-tool iits, the guide l? engaging in a proper slot in the said recess adapted to receive it. The tool is also secured to a transverse guide, which has sliding bearings on the upright posts. This piercing-tool, with the supporting and guiding parts, may be of one piece, or the recessed portion may be separate and fastened to an upper piece, U', by means of bolts or other devices, which pass through lugs on the ends of each part.

The reciprocating frame T is actuated by the cam V, which raises it, and also the cam WT, which gives it a quick downward motion. The two cams are placed side by side on the driving-shaft X, which has bearings in the upright posts. Both cams bear on frictionrollers.

On the cam V is a friction-roller arranged to throw the lever-arm Y up, it falling afterlward by its own weight to the shaft X. This IOO lever-arm Y is connected to a fulcrum-shaft, Z, having suitable bearings, A', fastened to and extending a short distance from the upright posts. 'Io this fulcrum-shaft is secured the shorter lever-arms B', which extend downward and are attached to the push-bars C', which extend through slots in the end of the bed to the heels7 of the die, as shown in Figs. l and 3. These bars are curved slightly upward, the slots in which they move corresponding to them. rIhe end of each bar is recessed, as shown, that they may engage the heels of the shoe after it has been formed, and lifting it as high as the upper bevel on the die, push it quickly forward, giving it impetus enough to force it through the opening B and into any proper receptacle.

The piercing-tool U is provided with two series of removable and separate beveled teeth, one series on either side of said tool, for the purpose of forming the nail-holes, and also fulling7 or creasing the shoe at one operation, the teeth that cut ythe nail-holes being longer than those that cut the crease, both be-y ing held in place by set-screws, as shown in Fig. 4.. Being removable they can be taken out and easily sharpened.

D represents connecting-rods between the carriage E and one on another machine of similar construction to the one described, the machines being preferably used double.

E represents the main driving-shaft having suitable bearings between the machines. On

' this shaft is the cam F', which alternately bears against the carriages, giving them a reciprocatory motion, as will be readily seen. The bearing-surface of the cam is made anti-friction by means of a series of rollers, as seen in Fig. 2.

The operation of the device is simple and easily understood. When the carriage is in the position shown in Fig. 3, a bar of iron properly heated is thrust through the slot in the side of the table and also the slots in the arms G till it is stopped by the other side of the table. The cam on the main driving-shaft then forces the carriage, cutting the bar at the inner edge of the slot K. The middle of the bar then engages with the toe of the die, and is there arrested, the ends being bent around to conform with the die by the pressure of the carriage on the arms and the inward or approaching motion given the said arms by the rollers engaging in the curved slots and the rollers engaging with the sides of the recess in the bed. ,The carriage is then drawn back by the cam F', operating on the carriage of the other machine, the said carriages being connected by the rods D'. The shoe having been shaped, the piercing-tool is then descended by means of the cam W, thereby forming the nailholes and the crease for receiving the heads of the same, as heretofore described. The cam V then lifts the tool, and also operates the lever-arm Y, which causes a forward and upward motion of the push-bars C', discharging the shoe through the opening B.

It will of course be understood that the operation just described was effected while the carriage was being drawn back. p

The shape of the cam F' allows the carriage to rest long enough for another bar to be 1nserted before the operation described is again resumed.

If desired, the main shaft and the transverse shaft operating the piercing-tool may be connected by suitable gear or by other well-k nown means.

Having thus described my device, what I claim is 1. In a horseshoe-machine, the combination of the frame carrying .the piercing-tool and ejecting mechanism, the anti-friction cams for operating the same, the piercing-tool provided with removable beveled teeth and adapted to t over the die, and the ejecting mechanism consisting of la lever-arm operated by a frlction-roller on one ofthe cams, and having one end xed to a fulcrum-shaft, the said shaft carrying lever-arms, which operate the pushbars adapted to throw the shoe from the die, the said bars movingin suitable slots in the end of the bed, all the parts operating to pierce the nail-holes in and full 7 or crease the shoeblank and to eject the same from the machine, substantially as described.

2. In ahorseshoe-machine, the combination of the recessed bed carrying a slotted plate on one end and having an openin g near the other, the said slotted plate on the bed, the reciprocating carriage moving on the bed, and operated by a cam on the main driving-shaft, the approaching slotted arms connected to said carriage, and having anti-friction bearings 1n the slots in the plate and at all contact-points, the beveled die, the piercing-tool having removable beveled teeth, the anti-friction cams operating the tool and ejecting mechanism, f

1rol

cessed on the ends and working in slots in the bed, all the parts operating to form horseshoevblanks from bar metal, to pierce the nail-holes and full the shoes, and to eject the finished shoe from the machine, substantially as described.

3. In a horseshoe-machine, the combination, with the recessedbed having a cutting-edge on one side of a slot therein, the slotted plate, and sliding carriage, of curved slotted arms, the edge of the slot in one of the arms forming a cutting-edge for separating the blank-bar, the whole operating substantially as and for the purpose speciiied.

4. Ina horseshoe-machine, the combination, with the recessed bed, the slotted plate, and the sliding carriage, of the slotted arms pivoted to the carriage, and guided by anti-friction bearings in the slots in the plate, and havin g all their contact-points provided with friction-rollers, substantially as described.

5. The combination, with the upright frame,

the beveled die having` a guide on its upper surface, and the shaft and cams, of the recessed piercing-tool tting over the die and receiving the die thereon, and the removable beveled teeth on the said tool, the parts operating substantially as and for the purpose specified.

6. In combination with the recessed bed, the upright frame, and operating cams secured to a shaft journaled in the uprights, the ejecting mechanism consisting of a long leverarm connected to a fulcrum-shaft, two short arms connected to the said shaft, and two bars connected to the short arms, and recessed at their free ends and adapted to slide in slots in the end of the bed, the whole operating to throw the finished shoe from the machine, substantially as described.

ed to the said shaft, and bars pivoted to the said short arms and recessed at their free ends, the bars being` adapted to slide in and be guided by slots in the bed of the machine, the whole device supported and operated substantially as and for the purpose specified.

9. Bending-arms for horseshoe machines, each arm having a proper curve, and provided near one end with a lateral slot, the bearingpoints of the arms all being provided with friction-rollers, substantially as and for the purpose specified.

l0.
